document.write( "Triangles ADC and ABC have COMMON altitude; therefore, the ratio of their areas is the same as the ratio of their bases |AD| : |BC| = .\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Since the sum od the areas of these triangles is 3440 square inches, \r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    the area of the triangle ADC is   =  = 1290 sq. inches;\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "    the area of the triangle ABC is   =  = 2150 sq. inches.\r\n" );
